摘要：

We report theoretical calculations for the beta-2p-asymmetry parameter in the photoionization of He(1s2) above the N = 2 ionization threshold. We use an extension of a method recently proposed [I. Sanchez and F. Martin, Phys. Rev. A 44, 7318 (1991)] that makes use of a Feshbach partitioning of the final-state wave function and an L2 representation of the coupled continuum states. Partial differential cross sections at emission angles 0-degrees and 90-degrees are also provided. Our results are in good agreement with the experimental data, thus showing the accuracy of the present method to study electron angular-distribution properties.
